How to Consult the I Ching with 3 Coins: Complete Beginner's Method

The I Ching — or Yi Jing, the Book of Changes — is one of the oldest oracles in the world, used in China for over three thousand years. Its traditional method, based on fifty yarrow stalks, demands time and a certain ritual focus. Fortunately there exists a faster, more accessible, and equally valid method: the three-coin method. This guide shows you exactly how to proceed, step by step, with a fully worked example. By the end, you'll be able to consult the I Ching on your own and read a hexagram without depending on an obscure manual.

Why three coins?

The three-coin method appears in China around the Han dynasty (3rd century BCE), as a practical alternative to the fifty yarrow stalks — much longer, far more ritualized. Where the stalk method takes about twenty minutes per consultation, three coins take five. The statistical outcome differs slightly (yarrow stalks produce fewer changing lines), but the oracular accuracy remains equivalent. For anyone beginning the I Ching, three coins are without hesitation the right entry point.

The principle is simple: with each cast, the three coins produce a combination of heads and tails whose sum designates one of four possible line types. Six consecutive casts build a complete hexagram — one of the sixty-four figures of the I Ching, each carrying its own message. To explore the oracle's broader workings, see the complete I Ching guide.

What you need before you start

Prepare little, but prepare well.

• Three identical coins. Any standard currency works — what matters is that the three be strictly identical so heads and tails hold the same value across casts. Chinese cash coins (round, square hole in the center) are traditional, but no obligation: three one-euro coins, three dimes, three quarters work perfectly.
• Quiet. Avoid consulting in haste or in the middle of distraction. Five quiet minutes is enough.
• Pen and paper. You'll be drawing six lines, from the bottom up. Trying to memorize almost always leads to errors.
• A question. This is the most important. An I Ching consulted without a clear question yields a fuzzy answer; an I Ching consulted on a sharp question yields a clear one.

How to phrase a good question

The quality of the reading depends 50 % on the quality of the question. Three principles guide good framing.

Avoid binary. "Will he come back?" or "Will I get the job?" are closed questions. The I Ching, by nature, answers in terms of movement and stance. Prefer: "What is the current dynamic of my relationship with X?" or "What attitude should I take toward this professional opportunity?"

Frame the time. A question without a time horizon becomes vague. Specify: "in the next three months", "this week", "during the current phase of my project". The I Ching answers better when it knows what interval to address.

Don't ask several things at once. One question = one topic. Avoid "And X, and Y, and Z?" framings that force the I Ching to arbitrate between your concerns. Pick the most pressing and ask it alone.

Write your question down before casting. This simple act often clarifies what you're really trying to learn.

The procedure in 7 steps

Here is the complete method. Follow it in order.

1. State the question out loud. Focus on what you truly want to understand. Hold the three coins in your joined hands, breathe calmly.

2. Cast the three coins on a flat surface. A table, the floor, whatever — just make sure the coins can roll freely and land flat.

3. Score the sum. Universal convention: heads = 3, tails = 2. Add the three coins. The total is always 6, 7, 8 or 9.

4. Record the line corresponding to the sum (see table below).

5. Repeat five more times. Six casts total — one per line. Record each line as you go, from bottom to top. The first cast gives line 1 (the lowest), the sixth cast gives line 6 (the highest).

6. Draw your complete hexagram. You'll have a figure of six stacked lines. If you've cast one or more changing lines (the 6s and 9s), draw a second hexagram next to it: stable lines (7s and 8s) stay the same, and changing lines flip to their opposite.

7. Identify your hexagram and read its meaning. Compare the six lines against the table of the 64 I Ching hexagrams to find the matching number. You can then read each hexagram's meaning on OracleNova.

The 4 line types

With each cast, the three coins fall into one of four possible combinations. Here's the classic convention.

Two ideas to remember:

• 6s and 9s are changing lines: they flip polarity in the second hexagram. Old yin (6) becomes yang, old yang (9) becomes yin.
• 7s and 8s are stable: they stay the same in the second hexagram. If you cast no 6s or 9s, there is no second hexagram — only the first counts.

Build your hexagram from the bottom up

This is the most common beginner mistake: drawing top to bottom, like writing a sentence. In the I Ching, you build from the bottom up, like a plant growing.

Line 1 (first cast) is at the bottom. Line 6 (sixth cast) is at the top. Lines 1 to 3 form the lower trigram, lines 4 to 6 form the upper trigram. A hexagram is always the meeting of two trigrams — that combination gives the figure its name and meaning.

To understand the eight base trigrams (Heaven, Earth, Water, Fire, Thunder, Wind, Mountain, Lake), see the I Ching trigrams page. They're the grammar of the oracle.

The role of changing lines

If your reading contains only 7s and 8s, you get a single hexagram — the message is clear, static, with no transformation. If your reading contains at least one 6 or one 9, you get two hexagrams: the first describes the current situation, the second describes where it's heading.

Changing lines are precious: they signal the tipping points of the situation. Each changing line has its own commentary in the classic text, to be read in priority — that's often where the practical key of the reading hides.

Three typical cases:

• No changing lines: stable situation, read the first hexagram only.
• One changing line: read that line's commentary plus the transition to the second hexagram. The clearest configuration for a beginner.
• Several changing lines: situation in rapid transformation, read the commentaries of changing lines in numerical order, then the second hexagram.

A complete worked example

Question: "What attitude should I take toward my current professional project, in the next three months?"

Casts (first to sixth):

1. 2 tails + 1 head = 7 → young yang ———
2. 2 tails + 1 head = 7 → young yang ———
3. 2 tails + 1 head = 7 → young yang ———
4. 1 tail + 2 heads = 8 → young yin — —
5. 1 tail + 2 heads = 8 → young yin — —
6. 3 heads = 9 → old yang ——— changing

Hexagram drawn from bottom to top:

Line 6  ━━━ ⨯  (old yang, changing)
Line 5  ━━ ━
Line 4  ━━ ━
Line 3  ━━━
Line 2  ━━━
Line 1  ━━━

Lower trigram: Heaven (three yang lines) — Qián. Upper trigram: Earth (three yin lines). Heaven below, Earth above = Hexagram 11, Tai (Peace).

With a changing line at position 6, the 6th yang line becomes yin, transforming the upper trigram from Earth to Mountain. The second hexagram: Heaven below, Mountain above = Hexagram 26, Da Xu (Taming the Great).

Reading: the current situation carries peace and harmony (Tai means balance between opposing forces, a fertile moment). The changing line at the top signals that by the end of the period, this peace will require an effort of discipline and patient accumulation (Da Xu = retaining great energy to deploy it at the right moment). Practical guidance: don't rest on present ease, actively prepare the next phase through rigor. To go deeper on these two hexagrams, see Hexagram 11 — Tai and Hexagram 26 — Da Xu.

3 beginner mistakes to avoid

Casting in the right order but reading in the wrong one. Build from the bottom up, but name the hexagram in the correct trigram order (bottom = lower trigram, top = upper trigram). Swapping the two trigrams changes the figure entirely.

Ignoring the changing lines. Many beginners record their hexagram and jump straight to the meaning, without checking for 6s or 9s. Yet the commentaries on changing lines are often the most actionable part of the reading. If you have a changing line, always read it.

Rephrasing the question after casting. If the answer feels off-topic, it's tempting to think "ah, but actually I meant to ask something else". Resist. The answer speaks to the question as asked — often more accurate than the one you thought you were asking. Note the answer, wait a day, re-read. Coherence almost always appears in hindsight.

In short

Three coins, six casts, paper to draw from bottom to top, and a well-framed question: that's everything you need to consult the I Ching on your own. The method is fast once learned — count five minutes of casting and ten to twenty minutes of interpretation for your first consultations. With practice, you'll recognize the most frequent hexagrams and reading will flow.
